Oswego police say they responded to a 911 call about 6:02 a.m. from neighbors on the 300 block of Hemlock Lane, alerting police that four masked men had broken into the house, armed with handguns, police said.

The men stole all six of the residents' phones and keys and physically battered two of the residents, police said in a news release from the Oswego Police Department. The victims included a female around 40 years of age and five males ranging between the ages of 17 and 21. Those injured in the incident were treated at the scene and refused transport to a hospital.

Police said in a later news release that the break-in "was directed toward the home and its occupants."

Detectives recovered a loaded handgun at the scene and are working to find its owner, said Dwight Baird, Oswego police chief. None of the home's residents claim ownership of the gun.

"The occupants of the house refuse to be interviewed by police at this time, and aren't being cooperative," Baird said.

Police said the suspects threatened the victims and then fled the scene in a recently purchased 2010 white Audi Q7, purchased out of state but bearing Illinois license plate V701752.

Illinois State Police say the suspects are driving the stolen car toward Chicago, and Oswego police say they'll continue working to recover the vehicle.

"We're still looking for them, and things are starting to wind down," Baird said.

Oswego police detectives are investigating and anyone with information should call (630) 554-1160.

Arrest and booking photos are provided by law enforcement officials. Arrest does not imply guilt, and criminal charges are merely accusations. A defendant is presumed innocent unless proven guilty and convicted.

A Justice Department investigation will allege sweeping patterns of discrimination within the Ferguson, Missouri, police department and at the municipal jail and court, a law enforcement official familiar with the report said Tuesday.
